So I have a path
p
and I can call for example is_regular_file(p)
and file_size(p)
on it but how to read that file into stringstream? (btw I need only to read it)
I assume you want to copy the entire file into the stringstream
.
std::stringstream ss;
ss << std::ifstream( p.string().c_str() ).rdbuf();
Here is a kind of inside-out demo:
Shadow:code dkrauss$ ./ssclone ssclone.cpp
#include <sstream>
#include <fstream>
#include <iostream>
int main(int, char *argv[] ) {
std::stringstream ss;
ss << std::ifstream( argv[1] ).rdbuf();
std::cout << ss.str() << '\n';
}
